When installed, were they installed using the enterprise MSI or the standard executable? I think the uninstall for the standard executable isn't an MSI and thus can't be removed using MSIExec.
I would consider using the Flash Uninstaller tool to remove any previous versions prior to installing the new version: http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html
It probably supports -silent as a parameter. Although I'm not sure, haven't tested.
